Hi,
OK, I am aware of the issue of the separation causing an elliptical
polarisation, that separation being needed to avoid detuning an
antenna that was designed for working alone.
What I had in mind was that instead of mounting the antennas
at 90 degrees to each other, mount at 80 ? or 100 ? degrees,
i.e. -40 ,+40 or -60 ,+60 degrees, or some other skew depending
on the spacing. Like an X, rather than a tilted cross.
Does that compute ?
